Title: Method of forming vertical type superlattice of compound semiconductor
Inventor: ANDO HIDEYASU
IPC: H01L29/06
Filed: 1989-09-05
Abstract: PURPOSE:To make it possible to form a vertical type superlattice, on which an AC layer and a BC layer are arranged, by a method wherein an A atom layer is formed on a part of the terrace width of the atom step of a substrate by controlling both feeding method of raw gas and film-growth conditions, and after a B atom layer has been formed on the remaining part, C atoms are adsorbed onto the A atom layer and the B atom layer. CONSTITUTION:First, an A-atom layer 11 is grown on a part of the terrace width of atom step of a crystal substrate 1 by controlling the feeding method of each raw gas A, B and C atoms and growth conditions, and then a B-single atom layer 12 is grown on the remaining part. C-atoms are adsorbed into an A monoatomic layer 11 and a B monoatomic layer 12, and an AC monomolecular layer 13 and a BC monomolecular layer 14 are formed. Accordingly, the growth and formation of the BC monomolecular layer exceeding the terrace width of atom step is prevented, and also as the above-mentioned layer is not formed shorter than the terrace width, one of the interface of AC/BC is especially made flat, and it is formed vertical to the crystal substrate without fail. As a result, a vertical type superlattice, which is orthogonal to the crystal substrate 1 and having excellent interfacial flatness, can be formed.

Title: Stencil printing device
Inventor: OTOMO TOMOYA
IPC: B41L13/04
Filed: 1992-08-27
Abstract: PURPOSE:To make it possible to print an image starting with the first sheet and prevent many sheets from being wasted by allowing a printing sheet to move back and forth several times and thereby pressing the same printing sheet to a stencil sheet several times. CONSTITUTION:The stencil printing device is composed of a printing drum 6, an ink feed roller 7 and a press roller 11 installed in contact with the peripheral surface of the printing drum 6 against the ink feed roller 7. In this stencil printing device, a printing sheet 20 transported from a sheet feeder part using feed rollers 13, 14 is pressed to a stencil sheet which is wound around the printing drum 6 by the press roller 11 to form a print image. Then the printing sheet 20 is moved back and forth several times by a transport direction switching claw 22, and the same printing sheet 20 is pressed several times against the stencil sheet. When data is printed again using the same stencil sheet or data is printed using a newly prepared stencil sheet, it is thus possible to obtain a print image of satisfactory quality starting with the first copy without being influenced by the time and environment in which the stencil printing machine is left alone.

Inventor: MASUISHI KOUICHI
IPC: B30B15/28
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To improve the reliability on the detection of abnormality in the action of an objective device by comparing a measured index value and a reference index value and discriminating whether the action of the objective device is abnormal or not, with large or small amount in the measured index value. SOLUTION: In an index value measuring part 3 when an one minute timer becomes time-up condition, a counter value of press shot number is made to the measured index value (c) and outputted to an abnormal action discriminating part 4. At this time, in the abnormal action discriminating part 4, the index value at the time of normally moving in the automatic pressing device before starting the action of this pressing device is inputted as the reference index value (b). In the abnormal action discriminating part 4, the measured index value (c) and the reference index value (b) are compared, and it is discrimited whether the action in the automatic pressing device is abnormal or not with large or small amount in the measured index value (c).  In the case the measured index value (c) is larger than the reference index value (b), (c>=b), it is decided to be normal, and in case of (c<b), it is decided to be abnormal.

Abstract: PURPOSE:To reduce the transmission loss of an optical cable for intra-office termination and to facilitate operation by carrying out the cord work of an optical fiber core at one terminal part, and providing a gas partition wall integrally with or closely to the fixation part of the cord. CONSTITUTION:The cord work of the optical fiber core is carried out at one terminal part of the optical fiber cable 72.

IPC: B22C9/04
Filed: 1988-09-14
Abstract: PURPOSE: To remove a pattern put into a sand-binder mixture at a relatively low temp. and to evade the intrusion of a decomposition product into a product by preparing this mixture at the time of casting in the cavity part formed by melting the pattern. CONSTITUTION: The sand sufficiently contains a non-refractory binder for setting the sand in order to form the casting mold and the ratio of this binder is as low as to allow the sufficient flow of the sand around the pattern. The resulted casting mold has the sufficient porosity to house and confine the decomposition product of the liquid and vapor of the pattern and has the hardness sufficient for maintaining a pattern shape after the removal of the pattern. The pattern 10 is first installed in a flask 11 and the sand-binder mixture 12 is poured around the pattern 10. The mixture 12 is set and the pattern 10 is dissolved by heating and is removed by outflow. This removal is executed at the relatively low temp. at which the material residue of the pattern 10 is made to remain in the sand mold (not the cavity of the casting mold).  Next, the cavity is filled with the molten metal and the metal is solidified. The casting metal is taken out of the casting mold.

Title: Device and method of machining periphery of opening of work
Inventor: JIYON ANSONII KATANIIZU
IPC: B23Q11/00
Filed: 1988-09-14
Abstract: PURPOSE: To prevent scrap from depositing in a workpiece such as a pipe by directing a jet of fluid over an opening of the workpiece to generate a low fluid-pressure region over the opening. CONSTITUTION: A pipelike workpiece 10 is held by a frame 30 and is rotated so as to be cut by a cutting-off tool 40 and chamfered by a chamfering tool 50. Since the scrap caused during this machining is liable to enter the workpiece 10 at its end opening 20, a first nozzle 60 and a second nozzle 70 arranged on the frame 30 direct a jet stream of air over the opening 20 to generate a low pressure region over the opening 20 so that the scrap is entrained in the air jet and is absorbed into a vacuum attachment 80. The scrap is thus efficiently cleared away or prevented from depositing in the pipelike workpiece 10.
